A little tip picked up from
Liam Foy Adrian Nida on #dragonflybsd on EFNet: If you have a 16-bit UTF file,
less will read it with ^@ characters all through the file. The pkgsrc package
converters/recode will allow cleanup like so:
cat file.utf16 | recode utf16..ascii > file.ascii
Update: Several people pointed out that
iconv can do the same thing.
